Abstract: The popularization and application of Severe Weather Auto Nowforecasting (SWAN) system is an essential way to improve the meteorological operation level. This paper introduces the building process and application of SWAN in Kunming Meteorological Bureau from four aspects: basic data preparation, system server platform construction, client installation and local business application. Through comparison and analysis, the difference between SWAN systems of Yunnan Province and Kunming City in terms of radar-related products and observation data of automatic stations is figured out: the timely rate of products, the density of stations and the accuracy rate of products in some areas are different, and it is pointed out that the SWAN system needs to be perfected. It is suggested that the products of provincial and municipal SWAN systems should be used together to make full use of their respective strengths and make up for their deficiencies, in order to improve the level of Severe Weather Auto Nowforecasting (SWAN).

1 概述
强天气短时临近预报系统(英文简称“SWAN”)是中国气象局推广应用的业务系统。昆明市气象局按照中国气象局和云南省气象局的要求,根据自己拥有新一代天气雷达的自身条件,率先完成可供全市气象部门使用的地市级SWAN系统平台的搭建。该系统在满足基层业务人员便易获取更多气象资料的同时,也提高了强天气短时临近预报预警的能力。而后,随着云南省级SWAN系统在全省气象部门推广使用,昆明市气象局业务人员发现,省、市两级SWAN系统产品各有优缺点,合理搭配使用能相互弥补不足,充分发挥各自的优势,对改善强天气短时临近预报预警能力有重要帮助。本文介绍昆明市SWAN系统平台的搭建和省、市两级该系统的搭配使用经验。
